QUIZ: How well do you know Frank Underwood?

Hopefully by now you’ve caught up with Season 1 of the Netflix series “House of Cards” and binge-watched its second season, which was released on Valentine’s Day. If not, be forewarned: Spoilers abound ahead. Fictional Democratic politician Frank Underwood is someone who keeps tabs on everything and everyone in Washington, but just how well do you know the series' main character?

Answer: D. Preparing for a fight and for good luck. When visiting Raymond Tusk in Missouri in Season 1, Tusk asks Underwood why he taps twice, Underwood explains: “Something my father taught me. It’s meant to harden your knuckles so you don’t break them if you get into a fight. It also has the added benefit of knocking on wood. My father believed that success is a mixture of preparation and luck. Tapping the table kills both birds with one stone.”
